Abstract

In the moulding of composite plastic material, in particular of foamed polystyrene coupled with rigid polystyrene sheet, the rigid material (2) is preformed, with the preformed portion being simultaneously separated from the starting material, and the preformed shaped portion is transferred to the preforming half-mould at the moulding step, in which the formed material is moulded by means of sintering and pulsed steam action on the preformed rigid material. The resulting piece is brought back to the preforming step (1) and a further portion of rigid material (2) is preformed on the foamed material, and this portion is then thermoset inside the moulding mould (3) on the foamed material, thus generating an article with two opposite surfaces made of a rigid material, between which the foamed material is sandwiched. <IMAGE>
